Mahydrofluoroolefins (HFOs) zvinhu zvisina kuguta zvakasikwa zvine hydrogen, fluorine uye kabhoni. Kusiyana nemahydrofluorocarbons echinyakare (HFCs) nemachlorofluorocarbons (CFCs), ayo akazara, maHFOs maolefins, anozivikanwawo sealkenes. MaHFOs ari kugadzirwa se "chizvarwa chechina" mafiriji ane mukana wakaderera wekudziya kwepasi rose unove 0.1% yeHFCs. Zvigadzirwa zveHFO zvine hupenyu hupfupi hwemhepo uye zvakarongwa sezvisina ODP (Ozone Depletion Potential) uye GWP yakaderera (Global Warming Potential), zvichipa imwe nzira isingakuvadzi nharaunda kupfuura maCFCs, HCFCs neHFCs.
Foam yepolyurethane inogadzirwa uchishandisa maHFO semushonga wekuputira inoshandiswa zvakanyanya muzvikamu zvemotokari nekuvaka muchimiro chefoam inochinjika uye yakasimba iri kutungamira kukura kwemusika weHFO.
